Sharpening a Groove

[hunter s thompson]

Does anyone know what the edge angle on a regular (non-tanto) groove is? You guys are always ready to help,but thanks in advance

 

[SPXTrader]

40 degrees inclusive IIRC. You using a sharpmaker?

 

[hunter s thompson]

Yes I am using a Sharpmaker. I also use some DMT stones unless im being lazy.

 

[SPXTrader]

Do you know the Sharpie trick when using the Sharpmaker?

 

[hunter s thompson]

Yes learned that from lurking around here. I thought i had better ask !st before I the Sharpmaker out and the OCD kicked in and I spent all day today working on my Groove. The wife ain't real happy right now been to the NASCAR races all weekend.Today is "Mothers" day.

Ha! Roger that! Great race last night!

If you want to go OCD on it, use the marker, take it to 30 inclusive, then put the 40 back bevel on it. Gets nice and sharp.

 

[hunter s thompson]

Its not that I want to get OCD on it, once I start it just kinda happens. Can I get you to explain a back bevel I think I have the theory down but not so sure in the application. It was a pretty good race but I hate what they have done to the track with the new surface. Makes passing pretty hard.

 

[SPXTrader]

Rather than trying to explain it, take a look here! They refer to it as a compound or double bevel.

Thanks for the help i really appreciate it. That makes a lot of sense I think I will try that.

I'm new to sharpening so please correct me if I'm wrong, but wouldn't the back bevel then be 30 degrees, not 40?

Yup. I think he meant to suggest applying a 40 degree "micro-bevel" to a 30 degree back-bevel.

[SPXTrader]

Yeah. What he said. Thanks for the clarification, 3G!

 

[3Guardsmen]

No problem, Don Vito.

the only way I don't get myself into sharpening trouble is to not let it get dull. I just don't trust all this angle stuff. I routinely touch up all my knives on ceramic rods and keep them hair popping. An elder maker once taught me to never let them get dull. I guess it only works, though if your not ou in the field using for heavy duty. For me, that sandvic is like butter to sharpen

Whats the "Sharp Maker trick"?

 

[svrider3]

Take a Sharpie(magic marker) color the edge..just the edge with it, then you run it
across a rod/stone. If you remove the color from the whole edge you're hitting at the
right angle. If not, just adjust until you do.

Hope that makes sence.

EDIT:Joe Talmadge says it better then me........

"If you want to determine if you are sharpening at the same angle that the blade already has, try this easy trick. Mark the edge bevel with a magic marker. Then go ahead and do a stroke or two on the stone (or take a stroke with your Lansky, or whatever). Now pick the knife up and look at the edge. If you have matched the edge angle exactly, the magic marker will be scraped off along the entire edge bevel. If your angle is too high, only the marker near the very very tip will be gone. If your angle is too low, only the marker near where the edge bevel meets the primary bevel will be gone".

Here's a good link for ya.

 

[SPXTrader]

...nevermind...too slow!

 

[J_Curd]

Yup. I reprofile it all to 30 degrees, and the marker trick is perfect, Im sick of staring at the edge closely to figure out whats going on. Good stuff.

great info guys...thanks

 

[hunter s thompson]

Thanks for all the info guys. I got a little OCD with the groove and the sharpmaker today. Its alot sharper now than when I got it from SMKW the other day. I think its going to replace my G10 leek as edc for a while.
